The following describes a stockpile of weapons from 1944 to 1974. From 1944 to 1958, there was a gradual increase in the number of weapons from 0 to about 6,000. From 1958 to 1966, there was a rapid increase in the number of weapons to a maximum of about 33,000. From 1966 to 1970, there was a decrease in the number of weapons to about 26,000. Finally, from 1970 to 1974, there was a small increase to about 28,000 weapons.

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

cool? what is the actuall ?

step-by-step explanation:

the answer to 3p+12m+8=23pm
